No. This has been a constant evolution since at least 2008, I want to say, when we started doing moderation. We actually were doing moderation when everyone else, like Facebook and the others, were not, because they believed it could cause them to lose their DMCA “safe harbour”. Now that time has evolved....
We were still willing to do it, because it was so important to us as a business that we wouldn't allow CSAM on the site. We did it even though we thought we could lose our DMCA safe harbour.
